CVE-2024-26601 Open this link in a new tabHow to fix?
Upgrade RHEL:9 kernel-core to version 0:5.14.0-284.77.1.el9_2 or higher.
This issue was patched in RHSA-2024:5066.
NVD Description
Note: Versions mentioned in the description apply only to the upstream kernel-core package and not the kernel-core package as distributed by RHEL.
See How to fix? for RHEL:9 relevant fixed versions and status.
In the Linux kernel, the following vulnerability has been resolved:
ext4: regenerate buddy after block freeing failed if under fc replay
This mostly reverts commit 6bd97bf273bd ("ext4: remove redundant mb_regenerate_buddy()") and reintroduces mb_regenerate_buddy(). Based on code in mb_free_blocks(), fast commit replay can end up marking as free blocks that are already marked as such. This causes corruption of the buddy bitmap so we need to regenerate it in that case.
